[PATCH] D25154: [libc++] Fix stack_allocator

[Eric Fiselier via cfe-commits]

EricWF updated this revision to Diff 74006.
EricWF added a comment.

Rewrite the patch entirely. Instead of using an actual "stack buffer" I've transformed `stack_allocator` into `limited_allocator<T, N>` which allows at most `N` elements to be allocated from it. This resolves the issues about stack usage but it doesn't help with the MSVC debug extra allocations.
